How to Troubleshoot Errors in Lindy Lindy makes automation seamless, but occasional errors can occur. This guide will help you quickly identify, understand, and resolve common issues, so your workflows stay on track.

Here are some possible reasons and fixes:
Missing Exit Condition : If the agent is handling a complex task or using multiple skills, it may not know when to stop. Fix: Define a clear exit condition, so the agent knows when the task is complete.Skills Issue : The agent may lack the necessary skills to finish the task. Fix: Assign the required skills, keeping the total below four skills per agent for most tasks.Prompt Issue : The instructions might be unclear or too vague. Fix: Refine the prompt to ensure the agent fully understands the task.

“My Email received trigger does not fire in test mode” If you email yourself & the sender and recipient email addresses are the same, it won’t trigger the Email Received trigger. This is intentional to prevent infinite loops and other unintended behaviours.
How to Fix: Use a different email address to test the trigger. If you’re testing a Lindy, send the email from a separate account instead of your own. For more details, refer to Lindy’s guide on email responding .
"Task Stopped Due to Insufficient Credits" If a Lindy task stops because of credit limits, it won’t automatically restart. However, you can manually resume it.
